Re: battery puzzle
I can only suggest you charge it again with the correct polarity and at 12 V (the charger will probably operate at about 14 V to do it) and try to recover the initial function again.
Keep a close eye on it at first in case it mis-behaves or overheats or something horrible.
A very long time ago, I charged a near-new motorcycle battery with the wrong polarity and left it charging overnight.
When I realised my mistake, I switched it back and charged it the correct way and it worked again OK for years. It did not have to turn a starter motor though.
What size of battery was it you have? is it nearly new?
Remember to switch the charger off before you remove the charger leads. I have painful recollection of neglecting that advice. It is a mistake I have not made since.
